I use QuickRes all the time to run 2560x1600 (anything higher is pretty much unusable) on my 2014 rMBP. I was wondering if it's ok to run at this resolution constantly?
It seems to work perfectly fine especially with heavier applications.
Whoa 13" is tiny. On the 15" the real estate is nice tho. Imagine if it was 17" running at 3840x2160. That would be like a full size desktop in a laptop.
